Comparison of the Dural Puncture Epidural and Conventional Epidural Analgesia Maintained Using Programmed Epidural Boluses for Labor Analgesia.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: Research indicates that the dural puncture epidural (DPE) technique offers quicker analgesia onset compared to the conventional epidural (EP) technique. Programmed intermittent epidural bolus (PIEB) is superior to continuous epidural infusion (CEI) for maintaining labor analgesia, providing better pain relief and less motor block. Few studies have explored if combining DPE with the PIEB offers additional benefits in analgesia onset, maintenance, local anesthetic consumption, and side effects compared to DPE with EP. We hypothesized that DPE, when combined with PIEB, not only speeds up analgesia onset but also improves neuraxial analgesia maintenance over EP. Patients and Methods: A total of 126 term nulliparous women with singleton pregnancies with a VAS pain score >50 mm and cervical dilation <5 cm were randomized to receive EP+PIEB or DPE+PIEB for labor analgesia, initiated with 15 mL of 0.0625% ropivacaine with 0.4 µg/mL of sufentanil using the EP or DPE technique (using 25-gauge Whitacre needle) technique and both maintained with the same solution for PIEB (fixed volume 10 mL, intervals 45 minutes, lockout interval 15 minutes) with labor analgesia. The primary outcome was time to achieving adequate analgesia, defined as a VAS pain score ≤30 mm. Secondary outcomes included pain scores, motor blockade, obstetric and neonatal outcomes, and satisfaction with analgesia. Results: Adequate analgesia was achieved faster in the DPE+PIEB group than in the EP+PIEB group (hazard ratio 2.409; 95% CI 1.670 to 3.474, Conclusion: DPE with PIEB accelerated onset time but did not improve maintenance of neuraxial labor analgesia over DPE with EP.
